In the US you can show in the hunters OR jumpers without a trainer. You just have to sign yourself as your trainer. The only reason they ask is if you get in trouble for something they'll know who to punish. For certain things the trainer gets punished along with the rider. Like mentioned above, make sure you know the rules!
Kind of a broad question and I have no idea what kind of show experience you have so I'll list a few things that come to mind first...
1) On show day make sure you check in with the gate person to put yourself in the order (esp if you're going to be going between 2 rings). Rated shows are usually bigger then schooling shows. I just got back from a 2 week A show that had over about 45 just in the .90 M's. There's no way the gate guy can get everyone in and out of the ring in an orderly fashion unless they assign a "spot" for you. The earlier you check in, the better spot you'll get. ie: if you're doing 2 classes a day you'll probably want to go late in the order in the first class and early the 2nd so you won't have to much lag time in between. The gate guy will make announcements about how many trips until you go and when your course walks will be. Usually at the beginning of each division, but sometimes it's at the beginning of each course change. But sure you're listening!
2) Make sure you are very familiar with the jumper tables so you know how to do your course/jump off (if there is one). At most of our schooling shows we usually just have Power and Speed and Timed first jump off... but at lots of rated shows they'll have a different table per day, depending on the division. This past 2 weeks they did Optimal time almost every day for the lower levels.
3) Just like everyone said, make sure you have everything you need. Tack, apparel, barn equipment, etc. The good news us, I've never been to an A show without venders. :) If you forget something, there's a good chance you'll be able to replace it. Remember you're going to transporting your horse's home for about a week and he's going to be working hard. Our horses all have rubber stall mats so they don't stand on concrete, we bring fans, hoses (lots of facilities have faucets but no hoses), etc. Don't forget to bring no-bows and standing wraps. Your horse will be need to be wrapped every night. I also use poultice, liniment, hoof packing and vetrolin for the my horses that jump bigger. Read your banned substances list though, some brands of the things I listed above have illegal things in them.
4) don't forget to have fun! I love the camaraderie and friendships I've made with other people who show in my zone. Don't know where you'll be but most likely there will be a grand prix and maybe even a derby. Take time to watch! Some of the shows have great exhibitors parties (some every night!). Enjoy it!
And take lots of pics and tell us all about it! Have FUN!
**I just saw that you're from Canada. I don't know where your show will be (where is it?) or if they're different then in the US, but everything i listed is fairly standard for the US. :) Sorry if it doesn't apply to you!
